We had been heavy "wipes" consumers in my family, but I read an article that suggested that some people might actually find wipes quite irritating. I didn't think this could be me, since my skin isn't generally sensitive, but I thought I'd try laying off the wipes for a week. Lo and behold, my little problem magically went away!
My family has also been through pinworms. If you have a child in daycare (mine was in Kindergarten when we were afflicted), that's quite possible.
Glad you solved the problem, OP.
For the other issues of not getting clean, you may want to try seeing a urogynocologist and see if you have prolapse.
Sits baths are also good.
